Now I'm getting somewhere!

I changed the ignition switch and battery and got the three best flights to date on this airplane and engine combination. It is still suffering boiling off of the carb between flights but with choking, the engine will start and run, even at the 98 degrees we had today.

The ignition switch seems unable to support the current draw of the ignition, especially after the battery is drawn down a little. Maybe the Vlach ignition wasn't bad after all.

I shall retime it and regap the plug.

Thanks again for your help
